Century Dictionary and Cyclopedia
- n. A machine for raising water, consisting of a wheel over which passes a rope or chain carrying a series of buckets which dip into the well and discharge at the surface. In other forms the buckets are fixed to the periphery of the wheel.
- n. The rotating part of the turbine wheel (using either steam or water) in which a jet impinges upon curved surfaces, called buckets, and imparts velocity and energy to the rotor which is fastened to the revolving shaft. These vanes, or buckets, are either cut or molded from the solid edge of the wheel, or are made separately and carefully fitted on the edge.
